CUTTER-HEAD FOR ROUNDING FELLIES.

j SPECIFICATION fel-ming peut ef Lettere Patent lNo. 249,121, dated November 1, 1881,

Application filed August fi, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN C. TUNxIcLIFn, acitizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new anduseful Improvements in (lutter-Heads for Rounding the Inner Peripheries of Vheel-Fellies; -and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specilication.

This invention relates to cutter-heads for dressing or rounding the inner peripheries of wheel-fellies; and it consists in the use of a loose collar journaled on the cutter-head shaft, and provided with projecting lugs adapted to enter the holes in the fellies for the spokes and press the felly away from the cutters, so that they will not act on it and leave it unrounded and not cut away around said holes.

The invention further consists in combinations and constructions hereinafter described, and set forth in the claims hereto annexed.

In the accompanying drawings, which illustrate my invention, and in which the same letter is used as a mark of reference for the same part in the different gnres, Figure l is a side elevation of a cutter-head embodying my invention, and of a felly, and also devices for holding and feeding the felly to the cutters. Fig. 2 is a sectional plan of the cutterhead iu the plane ofthe crooked line x x in Fig. l, seen from the right-hand side of said section-line. Fig. 3 is a perspective of the gagecollar. Fig. 4 is a perspective of the cutterhead. Fig. 5 is a perspective of a short section of a felly.

The construction and relative arrangement of the parts of theimprovement are fully shown and described herein 5 but it has not been thought necessary to show all of the parts of the general and common machine in which said improvements may be incorporated, and hence only those parts of the general machine are shown and described which are necessary to illustrate fully and clearly the method ot' applying my improvements to practical use.

A in the drawings shows a cutter-head carlied 0n a shaft, B, mounted in a suitable frame, and rotated byanyordinary mechanism, which rotating mechanism is not shown in the drawings.

The. cutters C have each an arc-shaped cutting-edge, c, a-nd are arranged in pairs, with a disk-shaped gage-collar, D, between the cutters of each pair. The gage-collar D is formed, as plainly shown at Fig. 3, of a circular disk, with a central hele, d, and side projections or lugs, d', each provided with laterally-projecting studs or tappets d. This disk D is loosely journa-led on the shaft B, between the cutters C, as hereinbefore described, and the circular part D of itsfperiphery rests against the inner side of the felly and acts as a gage to limit the depth to which the cutters may act on the felly.

E is a felly, F, a presser-roller, carried on one end of a spring,f, which is secured to the frame. (Not shown.)

Grisafeed-roller,journaledtotheframe. (Not shown.)

H is a presser-roller, carried on a spring, h, which is secured to the unshown frame.

I is a spring-roller, carried on a spring-bar, t', which is also secured to the unshown frame.

In operation the felly E is fed to and operated upon by the cutters, as shown at Fig. l, as follows: The felly is held against the unshown frame by spring-roller I, which rests against the side of the felly. The spring-roller H rests against the lower side of the felly and holds it up to the cutters, and the spring-roller F rests upon its upper side and holds its rear end down as it is fed forward by the feed-roller G. rEhe disk D, being free to turn on the shaft B independent of the cutter-head, will rest with its circular part D on the inner surface of the fel-l y and act as a gage to limit the cut of the cutters, as hereinbefore described, until one of the spoke-holes e advances so that the end of the adjacent lug d enters the hole e, and the tappets d are brought into contact with the inner face ofthe felly, and force the felly and springroller H downward, and thereby free the felly of the action of the cutters, as shown by dotted lines at saine figure. The tappets d will force the felly from the cutters gradually as the disk D is carried forward when the lug d is in a hole e, and the felly will return toward the cut- IOO ters gradually as the lug d is carried forward by the advancing felly, and thereby released from the hole e, thus giving the felly the forni on its inner side adjacent to the spoke-holes e, shown by Fig. 5. After a lug d escapes from a hole c in the felly, the felly will by its forward motion rotate the disk D until the next lugdcomcsinto contact with thefelly, as shown by full lines at Fig. l, where the lug will stand (the felly sliding on the periphery D) until the next hole e approaches, and the adjacent lug d' drops therein to again force the felly away from the action ofthe cutters, as shown by the dotted lines, and as hereinbefore described. The lugs d may be variously constructed with shoulders, or otherwise, as equivalents of the lugs d.

The shape of the cutters, and the matter of a fixed gage-disk located between the cutters, is shown and claimed in an application I have executed oi' even date herewith for improvements in cutter-heads, and hence I do not claim the shape ofthe cutters, nora fixed gage-disk herein; but

What I claim as new is.

1. In a cutter-head for rounding the inner peripheries ot'wheel-fellies, in combination wi th the cutters, a gage-disk loosely mounted on the cutter-head shaft, and adapted to be rotated by contact with the advancing felly, to bring lugs or projections thereon into contact with the spoke-holes in the fellies, whereby the felly and cutter-head may be forced apart adjacent to said holes for the spokes, substantially as and for the purpose specified.

2. In combination with a cutterhead having cutters C, a gage-disk having a circular portion, D', and projecting lugs d', adapted to force the felly from the cutters, substantially as and for the purpose specified.

3. In a cutter-head having cutters() in pairs, a gage-disk loosely mounted on the cutterhead shaft between the cutters of each pair, and provided with projections adapted to force the stni` being operated upon away from the cutters at intervals, regulated substantially as and for the purpose specified.

4. In combination with a cutter-head having cutters C, a gage-disk having a circular portion, D, and projecting lugs d', having laterally-projecting lugs d, substantially as and for the purpose specified.

5. In a cutter-head, in combination with the cutters, a disk loosely mounted on the cutterhead shaft, and provided with means, substantially as described, whereby it is adapted t0 act as a gage to limit the depth to which the cutters act on the stuff, and also provided with projections or equivalents adapted to fome the stuffaway from the action ofthe cutters at given places, substantially as and for the purpose specitied.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN C. TUNNICLIFF.
